To rtZZ whmn it may concern:

Be it known that I, LEwIs J. PHILLIPS, a citizen of the United States,and a resident of Foss, in the county of \Vashita and Territory ofOklahoma, have invented a new and Improved Alarm Attachment .forSelf-Binders, of which the following is a full, clear, and exactdescription.

The invention relates to self-binding harvesters; and its object is toprovide a new and improved alarm attachment for self-binders arranged togive a signal or alarm to the driver to stop the harvester in case thetwine knots or is for other reasons prevented from feeding properly andas called for by the binding mechanism, and to allow suflicient twine topass through the binding mechanism for completing the binding of thegrain in the harvester at the time, and to prevent the twine from beingbroken, thus requiring no rethreading of the twine.

The invention consists of novel features and parts and combinations ofthe same, which will be more fully described hereinafter and thenpointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate cor responding parts in all theviews.

Figure l is a perspective view of the improvement, showing the parts innormal working position. Fig. 2 is a like view of the same, showing theparts in position after giving the alarm and Fig. 3 is a sectional planview of the improvement.

The twine A, contained in a twine-holding receptacle B, extends throughan eye B, formed in the cover B of the receptacle B, and the twine thenpasses downward and through an eye O, formed or secured on a rod D,mounted to slide in suitable bearing E, shown attached to the outside ofthe receptacle B. The twine after leaving the eye O passes upward andthrough an eye F, arranged at or near the top of the receptacle B, asplainly indicated in Figs. 1 and 2, and the twine then passes from thiseye F to the binder mechanism to bind the grain into sheaves in theusual manner. On the out side of the receptacle B is mounted an alarm,preferably in the form of a bell G, having a hammer H for sounding thebell, the hammer being in the form of a lever fulcrumed on thereceptacle B and pressed on by a spring I, the tension of which can beregulated by a suitable screw I. or other means. The free end of thehammer H extends into the path of a projection J, secured to or formedon the rod D a distance above the eye O, as plainly indicated in Fig. 1.

Normally the several parts are in the posi tion as illustrated in Fig.1, so that the twine A can readily pass from the twine-holdingreceptacle B to the binder mechanism to be used for tying the grain intosheaves in the usual manner Now in case the twine becomes knotted withinthe receptacle B, and hence does not feed properly, then the pullexerted on the twine by the binder mechanism causes an upward pull onthe eye C, so that the rod D is moved upwardly in its bearing E, and theprojection J engages and imparts a swinging motion to the hammer Hagainst the tension of the spring I. The projectionJ in its upwardmovement finally passes the free end of the hammer H, so that the latteris quickly returned by the action of the spring I, and consequently thehammer H sounds the bell G, thus giving a signal or alarm to the driverof the harvester, to stop the latter.

From the foregoing it will be seen that the alarm or signal and themeans for actuating the same are located intermediate the twineholdingreceptacle B and the binder mechanism, and the twine is used to actuatethe said means and the latter to actuate the alarm in case the twine isprevented from feeding properlythat is, when the twine becomes knottedin the twine-holding receptacle Bor other causes prevent the twine frompassing freely out of the receptacle B to the binder mechanism.

As the projection J is directly under the free end of the hammer H, thelatter is actuated and the alarm is sounded immediately after the rod Dbegins to slide upward; but as the harvester does not come immediatelyto a standstill provision is made to allow the rod D to slide furtherupward in the bearing E to bring the eye O nearer to the eyes B and F,thus permitting a suflicient length of twine to pass to the bindermechanism to bind the grain contained in the harvester at the time.

The pull exerted by the binder mechanism 1 twine by the binder mechanismcauses the on the twine A is ordinarily not sufllcient t0 IIO twine tolift the rod D for sounding the alarm and for still feeding a length ofthe twine to the binder mechanism until the harvester comes to astandstill. It will further be noticed that by the movement of the rodD, as described, the twine is not liable to break, and consequently atedious rethreading of the twine is not required. After the oper atorstops the machine the twine contained in the receptacle B can be readilyput into proper shape, after which the rod D is returned to its normalposition. (Shown in Fig. 1.)

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. An alarm attachment for self-binding harvesterscomprising a twine-holding receptacle, a rod mounted to slide on theoutside of the said receptacle, the rod having an eye for the passage ofthe twine from the said twine-holding receptacle to the bindingmechanism of the harvester, said eye being out of the direct line of thepassage of the twine from the. twine-holding receptacle to the bindingmechanism, an alarm, and means whereby it is actuated by the said rod onthe latter being moved by the twine at the time the latter is heldagainst movement in the twine-holding receptacle.

2. An alarm attachment for self-binding harvesters comprising atwine-holdin receptacle, a re d mounted to slide on the outside of thesaid receptacle, the rod having an eye for the passage of the twine fromthe said twine holding receptacle to the binding mechanism of theharvester, and an alarm comprising a bell and a spring-pressed hammerfor the same, and adapted to be engaged by a projection on the said rod.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LEl/VIS J. PHILLIPS.
